Title: Method and device for measuring specific charge of toner particle
Inventor: TEJIMA TAKASHI
IPC: G01N27/60
Filed: 1986-06-17
Abstract: PURPOSE:To measure the specific charge of toner particles with high accuracy by measuring the moving speed of the charged toner particles in an electric field in a single direction as a Doppler frequency. CONSTITUTION:A measurement position P is set at an almost center part between parallel electrode plates 1a and 1b and the direction of the electric field is set in a toner particle falling direction. A laser beam 6 from a laser light source 5 is split by a beam splitter 7 into two beams 6a and 6b which are nearly equal in intensity and those two laser beams are passed through the 1st lens 8 to cross each other at the measurement position P. Scattered light 9 from the measurement position P is guided to a detector (photoelectric converter) 12 through a slit, a pinhole 10, and a condenser lens 11. Then photoelectric conversion is performed and the vertical moving speed of the toner particle is measured as the Doppler frequency. This measurement is repeated while the electric field is varied and the specific charge of the toner particle is found from those measured values.

Filed: 1991-06-12
Abstract: PURPOSE:Since valinomycin is a cation selective ion channel, the concn. gradient between aq. KCl solns. is larger than in the case of the absence of the valinomycin and, therefore, the membrane potential of a lipid bimolecular membrane increases correspondingly and a potential-sensitive ion channel is driven by as much as the increased membrane potential of the lipid bimolecular membrane and, therefore, the auxiliary voltage to be impressed to this lipid bimolecular membrane can be lowered. CONSTITUTION:The lipid bimolecular membrane 31 is constituted of lecithin contg. the valinomycin at 10<-3>M concn. The one surface of this lipid bimolecular membrane 31 is brought into contact with the aq. KCl soln. 21 of 5mM concn. and the other surface is brought into contact with the aq KCl soln. 25 of 100mM concn. Alamephicin of 10<-9>M is dissolved in the aq. KCl soln. 21 of 5mM concn. to incorporate the potential-sensitive ion channel consisting of the alamephicin into the lipid bimolecular membrane 31.

Abstract: PURPOSE:To facilitate the processing of outputs, by satisfying prescribed conditions in the range detecting device for camera which focuses the reflected light from an object due to the light, which is projected from a light emitting element, on a one-dimensional photodetector. CONSTITUTION:The light from a light emitting element LED becomes parallel beams through a lens L1 and is projected to an object to be photographed, and the reflected light is focused on a one-dimensional photodector (PSD) through a lens L2. When the base length between lenses L1 and L2, the length between electrodes A and B of the PSD, the closest focusing distance of the camera, and the length between surfaces of lenses L1 and L2 and the PSD are denoted as (d), (e), lm, and (f) respectively, elm/11d>=f  is satisfied to obtain relation l= (df/e)i1/i. That is, a lengh (l) to the object to be photographed proportional to the ratio i1/i2 of currents i1 and i2 outputted electrodes A and B. An output V4 of a processing circuit constisting of operational amplifiers A1-A3 is proportional to (l), and thus the processing of outputs i1 and i2 of the PSD is facilitated.

Filed: 1980-10-06
Abstract: PURPOSE:To adjust a clock to the least error condition by altering a frequency dividing ratio in accordance with an error or the error of precision of respective clocks. CONSTITUTION:An output signal of a reference oscillator 1 is input into a display 5 for time by way of a frequency dividor 2 and a counter 3. Now, as a ''reset to zero'' signal for second plate is so input into a terminal 9 as to be set by a time signal, then a counting value in a place for the second is retained in a retaining circuit 6 and the place for second in the counter 3 is reset. Further, the retained content is operated together with the corrected condition, which is corrected at the time when the former ''rest to zero'' signal for second place generated, through a operating circuit 7. Therefore, a frequency dividing ratio, which is to be corrected with a correcting circuit 11 for the frequency division, is controlled in accordance  with the new corrected condition, thereby, the frequency dividing ratio of the frequency dividor 2 is altered.

Filed: 1981-09-07
Abstract: PURPOSE:To reduce the heat load per unit area of a tube and consequently prevent the tharmal deformation of the tube by a structure wherein the inside and the outside diameters of a tube located at the upstream side of the stream of high temperature working fluid are rendered to be relatively larger than those of a tube located at its downstream side in the multitubular heat exchanger for once-through heat exchanger. CONSTITUTION:As for a group of tubes 14, the inside and the outside diameters of the tubes 14A located at the upstream side of the stream of high temperature working fluid are rendered to be larger than those of the tubes 14B located at its downstream side. Owing to the structure as mentioned above, the high temperature working fluid collides first of all with the tubes 14A with larger inside and outside diameters. At this time, becuase of the larger diameter of the tubes 14A or the larger flow rate of low temperature fluid passing within the tubes 14A and of the consequent larger heat capacity of the tubes 14A, the tubes 14A can transfer a large amount of heat and can suppress excessive vaporization, resulting in enabling to reduce the heat load applied to the wall of the tubes 14A. Owing to the structure as mentioned above, the thermal deformation of the tubes 14A due to the heat load can be prevented.

Title: Method for evaluating electrical insulation oil
Inventor: AMIMOTO TAKESHI
IPC: H01B3/20
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To evaluate deterioration of insulation oil by increasing the temperature of an electrical insulation oil and measuring the number of chemiluminescence, obtaining a specific expression for indicating the relationship between the inverse number of temperature and the number of chemiluminescence, and performing judgment from the number of chemiluminescence at a constant temperature and a constant in an expression. SOLUTION: The temperature of an electrical insulation oil is increased by heating and the number of chemiluminescence and a measurement temperature during this period are measured, thus converting into Arrhenius plot with the abscissa as an inverse number X of the measurement temperature (absolute temperature). The Arrhenius plot can be regressed nearly linearly, a regression expression Y=A.exp(-BX/ R) (R: gas constant, A, B: constants) is established, and the constant B is obtained from these. The constant B indicates an activation energy. Further, the number of chemiluminescence at an initial temperature before temperature increases is obtained from the regression expression. The value is the number of chemiluminescence while an energy from the outside is small and indicates the current degree of deterioration of an electrical insulation oil.  This method allows the number of chemiluminescence to be measured quickly, thus the degree of deterioration of the electrical insulation oil can be quickly evaluated.
